Deletion of Communication Containers

A subject deletes a channel, group, workspace, conversation, mailbox folder, discussion board, or other communication container to remove the messages and associated context held within it.

Deleting a communication container may remove or obscure a larger body of evidence than deleting individual messages. The affected records may include message content, participant lists, timestamps, thread relationships, attachments, reactions, membership changes, and links to other organizational material.

The subject may delete the container after communications associated with an infringement have concluded, after participants have left the group, or after the subject becomes aware that the communication environment may be reviewed. They may also rename, archive, or move the container before deletion to make it more difficult to identify.

Investigators should establish who created, owned, administered, archived, and deleted the container; when the deletion occurred; which participants and messages were affected; and whether the activity followed an alert, complaint, investigation, or other relevant event. Platform audit records, retention systems, backups, legal holds, exports, and participant devices may allow the deleted content or surrounding metadata to be reconstructed.
